I have two Bettas in larger bowls. Due to space restrictions, I will be setting-up a couple of small tanks near them. My concern is that these two guys will be more interested in jumping with more places to jump to. Anyone know where I can find some bowl covers or any other creative solution?

Yes, I've thought about moving them to more easily covered tanks! But my older guy is extremely happy in his bowl. He's very territorial about it (flares like crazy whenever anyone gets near it!) and he's a bubble blowin' fool. It's one of those, "Why mess with a good thing?" situations.

Anyway, I found a guy on etsy that sells an acrylic cover, but I do not like that there are only very tiny airholes around the edge of the cover. I'm looking for something more breathable, but not a metal screen!

I could be wrong, but I think that if you want to cover the bowls, it doesn't matter how big of airholes are in the cover or anything, just as long as the cover doesn't come in direct contact with the water (like, floating right on it)

The other thing I had worried about with the acrylic tops was water temperature as I use a plant light above these bowls. Not only would the top magnify the light, it would cutdown on air exchange and thus increase the temperature. Makes me nervous.

The footies idea is genius though. Completely breathable and it shouldn't filter too much of the UV.
